Toowoomba Regional Council said Council officers were satisfied that the increased bacterial numbers were due to an environmental phenomenon rather than contamination of the dam water.
Council will close entry gates to Loveday Cove and the Cooby Dam wall picnic areas and signage will be put in place indicating the areas are closed to the public until further notice.
All reticulated water within the Cooby Dam Wall picnic areas, including taps and toilets, are untreated and therefore poses a risk to human safety during periods of high bacteria levels.
Council will undertake daily monitoring of these levels and will re-open both locations as soon as measured levels are below the recognised safety standards.
The bacteria represent no risk to drinking water supplies as they are removed by the water treatment and disinfection process.
Additional testing will be carried out on a regular basis to monitor the numbers of E.Coli bacteria.
